| Abstract: | Co-author: Ileana Streinu (Smith College)
O'Keeffe proposed generalizing the graph of the sodalite tetrahedral structure to arbitrary dimension by taking as vertices the holes of the A*d lattice sphere packing and connecting nearest neighbours. A second d-periodic graph is obtained by replacing vertices with d-simplices which share one apex when corresponding vertices are connected by an edge. We investigate the geometric deformations of these two related periodic structures. |
